 Today we're going to work on WF-3620, the printer use original epsomink and the black and the yellow are clogged. The black is more severe, there's no black coming out and the yellow has missing lines. So we just do a standard flushing, we get a piece of paper towel and we fold it three times and then we put underneath the printer and then we move the cartridge carriage over. If you don't know how to call the freed carriage, what you do is you plug the power in, once it starts moving to the middle, you disconnect the power. So we start with less aggressive flushing. I'm going to use this flashing tube, which looks a little bit weird and you can get those from BCH. You go to accessories and tubing and it's this tube. It comes with a bigger tube and a smaller tube. What you do is you slide the smaller tube inside the bigger tube and then the smaller tube will face the ink intake of the printer. So you push the small tube on the printer and then you fill the tube with cleaning solution or water or ink. Here we fill a clear ink which doesn't have any color. Then we just stir it and get any air bubble out. Then we just leave it. Some people leave it for a day, some people leave it for a week and just check periodically to make sure there's some fluid in the tube. So the second day we can see the result. We have magenta, cyan and yellow coming out. My concern is that there's no enough black coming out. So I'll need to flush it before I put the cartridge in. So go to the same routine. Get a piece of paper towel, fold, fold, fold in the middle. Now we remove the tubes. The second method is a more aggressive version of flushing. We'll need an unclogging syringe with a tube and some fluid. You can use ink or water or a cleaning solution. In this case we use a clear ink. So if something goes wrong, we don't splash ink everywhere. So we're going to attach the end of the tube to the ink intake. And then just push the liquid through. And do not push too hard. Oh, it's really easy. So this one is not clogged. I'm surprised. So maybe it just doesn't have ink. Or it's right on clogged last night. And since I already did black, why not just finish others? It's flush. Good. That's the black I want. Now we're going to get cartridge ready. We're going to use a BCH-RCEPT-252 XL. The first thing we do is figure out which one is the air plug. Which one is the refill plug. It's pretty easy to see. So there are two holes. One is plugged with a clear plug. Another is plugged with this color plug. So for the hole in the front, you can see if I stick a needle in, it goes pretty far. So it's pretty easy to fill this chamber. But for the one in the back, you cannot get into too much. So this is air hole. So this is refill hole. This is air hole. And when you have the printer in operation, you should keep the air hole open. So this hole should be open. And you should plug the refill hole. So after I refill it, I'm going to plug the color plug back into here. And I'm going to just keep the clear plug somewhere safe. So in the future, if I need to move the printer to a different state or shape it to somebody, I can plug this back. So the ink will not spill. But for the rest of the lifetime of the printer, you probably will not need this plug. Somebody will ask me why we put the color plug in the air hole. So why don't we just put it in the refill hole and ask people to remove the color plug. And we kind of force you to have to move this plug. Otherwise, if I put a clear plug here, you will never, not never. There are some people who will never think about removing this plug. So we kind of force you to put this out. Okay, this is the philosophy behind it. Okay, so with that side, let's refill. And don't worry about this piece of plastic. And when you punch it in, the printer will break this. There are lots of horror stories saying that you shouldn't use the dye ink in a pigment cartridge. Actually, you can. And I am going to post another video to show you the test with that. If you know how to do it, you can. If you don't, you don't. You may ask what happens if you refill through the air hole. Nothing happens. The refill hole is connected to the air hole. It just makes your life a lot harder to do that way. I have a customer actually spend two hours to refill through the air hole. So that's what's going to happen. Okay, now we plug the, we plug the plug for the refill hole. Okay, we got started without cartridge first. And pay attention to this first error message, which says there is no cartridge. And what it says is it cannot detect those cartridges. This error is really similar to another one that we're going to see pretty soon. So this one says ink cartridges are not installed correctly. Push down and make sure you hear a click. And also pay attention, when you press it down, the printer can detect it. And that cartridge is going to light up on the OEC screen. Okay, for the new cartridge, you might see this. It cannot recognize the following cartridges. So since they said it cannot recognize. And we will proceed to try to just wiggle it a little bit and see if it can detect it. Maybe just a bad contact with the printer. We do receive a customer report on this. So the first thing we try is, we try just open and close the lid. See if we can whip the printer up. We have to see if we don't know exactly why this happened. But here's something that we can try. So the first one doesn't work. Just open and close the printer. Just make sure every time you read the error message. Because the writer error message is really, really similar. So the second thing we tried is we remove and then reinsert the cartridge. So we removed it. Now we press it back. Because every time we press it back, that disappear. Okay. And then we just try it again. This error is a little bit different than the others. The first few errors says the cartridge cannot be recognized. That means the computer cannot tell if there's cartridge not. But this one says the black cartridge is not installed correctly. But if I check the ink level, the other cartridges show the ink level. So the other cartridges are installed correctly except the black one. You might get some error in here. Normally what I do is I shake it. So get some error bubble out. Basically I'm just taking it out and reinsert it. It still doesn't work. Then I found out there is a piece of plastic rubber stuck on the black cartridge. So I thought that may be the reason. Okay. This is the happy screen. So you have not installed the genuine Epson ink cartridge. You can see the error is pretty similar to the other errors. That said, there's something wrong. This is intentionally designed to scare you. So basically when you read it, yeah, this is not genuine Epson. So just a proceed. And there was a quality of the error or reliability is not going to be as good as Epson. Yeah, right. Continue use of, yeah, of course, that's why we do this. And the ink level. We're going to update this printer with a newest firmware. However, do not do this at home. Once you get a printer with a refillable cartridge, do not install any update and disable auto update. Epson has been known to search and kill refillable cartridges. So you don't want to, you don't want their update at all. We could just use the absence of building cleaning routines. We use it three times then we do three times again. But in this case, we kind of in a hurry. So we decided to flush the printhead again. So we pretty much flush it twice in an hour. And out of sudden, we have this problem again. If we read the error, the cartridge cannot be recognized. That means the printer cannot detect cartridge. But if we open up and just do a cartridge check, and they will tell us the cartridge are there installed correctly. And then when we try to print a page, it goes back to cartridge cannot be recognized error again. So we tried all the tricks taking cartridge out and putting back in. Another thing to check, for example, if the printer compliant Cyan and Magenta cannot be recognized. Take a look of the pin in the back. See the Cyan and Magenta pin are a lot higher than others. It turns out the absence pin can be moved up and down. So if we move all the way up, it cannot have a good contact with the circuit board in the back. So when you take the cartridge out, make sure you pull the pins all the way back and then pull the cartridge out. Otherwise, you may still connect to the pin. If you do it often enough, you could end up with a pin like this. So the one on the left is working one. The one working on the right, you can see, it's missing the bottom ones in the back. So if you only see the in front, they all look the same. But because you push it down all the time, the one in the back get weird out. I want to see through that part. See that brass one? It actually broke in front of me. That's why the Cyan doesn't show Cyan. So while this thing broke, it fell into the printer head. So also just make sure all those pins are pushed down and connected. This time after we put them in, we did a check and they cannot recognize them anymore. Try to take them out and put them back. This time we're greeted with a happy screen. You are not installing a genuine Epson cartridge. So the printer is happy with those cartridges again. We could continue without a problem solved, but immediately it's back to cannot recognize the cartridge again. We try to remove and install again, and it still doesn't work. This is beyond frustration, so we stop and look elsewhere for inspiration. We drank beer. My friends and I, the boys and girls, yes, we drank beer. I liked beer, still like beer. Sometimes probably had too many beers and sometimes other people had too many beers. We drank beer, we liked beer. What do you consider to be too many beers? I don't know. You know, whatever the chart says. So we went to a local establishment to check out their chart. So have this printer have problem recognizing the cartridges? So it doesn't matter what cartridge we put in, whether it's OEM or third-party cartridge. So let's say we're putting a magenta cartridge. You can see we're putting a third-party black. Yeah. So I think what happened is because we flooded it, we flushed the printer twice in a row. So there's some moisture gets into the cables inside the circuit board on the cartridge carriage. So if we just let it dry for 24 hours, let the moisture get out and the printer is back in action again. You still can see some moisture on the roller that had a mark on the paper. Everything else looking pretty good. So we did a big batch of printing and you can see it says ink is low. This is just a warning. The printer actually doesn't know how much ink is in the cartridge. It goes by how many pages printed. So they store this information on the cartridge chip. So for example, if the chip says zero and the printer will think it hasn't printed any pages so it will show a full tank of ink. And the BCH cartridge are there equipped with ARC chip which is auto-reset chip. So it's numbered from zero to the max then it rolls back to zero again. And as a consequence is you cannot set the number of chip yourself. So if you say ink is low you take the cartridge out and refill it. You put it back. The printer will still think ink is low because the page number hasn't reached the maximum number yet. It hasn't rolled back. Okay, this is what happens if the chip rolls back to zero and the printer actually cannot detect the cartridge again. The reason is the page number rolls back to zero. In this case it's black. However, the printer thinks it hasn't taken the cartridge out and put a new cartridge in. So how come to zero? So the printer got confused. All you need to do is pretending you are changing the cartridge. Actually most of the time I take this opportunity to take the cartridge out and fill it up to the maximum and then put it back. You can see each time it's trying to get you to use the real Epson ink. You have not installed genuine Epson cartridge. And now you can see the black level is full. Right now if you take other colors out and refill it and you will still see this ink level. It's not going to show the new level. So we go back to printing and soon there will be another cartridge depleted and then we take it out and fill it up and put it back and work again. So the previous owner printed 600 pages using the Epson ink and the printer got clocked and we can't un-clock today and we're going to print 300 pages. So what are we going to do with 300 pages of restaurant menu? Free lunch. I hope you enjoy this video. Visit www.bchtechnologies.com or locally at Greensboro, North Carolina. Thank you. Cheers.
